Question

A 0.13-kg k g baseball moves toward home plate with a velocity v⃗i v → i = (-37 m/s m / s )x^ x ^ . After striking the bat, the ball moves vertically upward with a velocity v⃗f v → f = (28 m/s m / s )y^ y ^ .

A) Find the direction of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 msms.

B) Find the magnitude of the impulse delivered to the ball by the bat. Assume that the ball and bat are in contact for 1.5 msms.

C) How would your answer to part B change if the mass of the ball were doubled? (is it 1. triple in magnitude, 2. double in magnitude, or 3. impulse would not change.)

D) How would your answer to part B change if the mass of the bat were doubled instead? (is it 1. triple in magnitude, 2. double in magnitude, or 3. impulse would not change.)
